Solution
Explanation:
Alkenes and alkynes are chemicals that decolorise bromine water. Bromine water’s orange colour diminishes after reacting with alkenes or alkynes, indicating decolorisation. Because cyclohexane is not an alkene or alkyne, it effectively removes the colour from bromine water. Similarly, phenol and aniline decolorise bromine water through an electrophilic substitution process.
